Matched pair trillion or triangular brown semi precious gemstone Royal Imperial Jasper designer cabochons with 18 mm sides by 3.5 mm thick.
These stone cabochons weigh about 8 carats each.
Royal Imperial Jasper comes from north of the border between Jalisco and Zacatecas, Mexico about 50 miles north of the city of Guadalajara.
Royal Imperial Jasper is found in small nodules with a soft white chalky "skin", as opposed to Imperial Jasper which is similar in colors but found in large veins and bigger pieces.
The material is considered a fine porcelain jasper and it makes wonderful patterned, unique cabochons with a great polish.
